Bump react-native 0.83.0→0.84.0, react 19.2.0→19.2.3, @react-native/* 0.83.0→0.84.0, @react-native-community/cli* 20.0.2→20.1.1 across detox, test app, and demo app. Fix demo app MainApplication.kt to use modern pattern (load() + applicationContext). Add RN 84 Buildkite CI pipelines and move REACT_NATIVE_COMPAT_TEST to RN 84 jobs. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

RN 0.84 removed NotThreadSafeBridgeIdleDebugListener and the addBridgeIdleDebugListener/removeBridgeIdleDebugListener methods from CatalystInstance. Use reflection to interact with these APIs so the code compiles against any RN version. On RN 0.84+ (where the API is absent), the resource gracefully falls back to reporting idle, since bridge monitoring is only relevant for old architecture which is being phased out.

The previous loadReactNative(this) call was handling SoLoader initialization internally. After replacing it with load(), SoLoader must be initialized explicitly to avoid IllegalStateException. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
